Spain to publicly name fuel stations exploiting Iran war aid as new discount begins

New regulatory powers

A reform of Royal Decree-Law 7/2026, approved on Monday and in force from today, extends CNMC oversight to all fuel wholesale operators. Previously only operators with refining capacity in Spain had to report cost and price data. Now every wholesaler must disclose real costs and sale prices until 31 December 2026; failure constitutes a serious infringement. The CNMC will monitor profit margins at every service station to detect unjustified price rises.

How the blacklist works

If the CNMC identifies a station where price increases cannot be explained by higher costs, it will notify the operator and request justification. Should the deviation remain unaddressed, the station will be added to a public list on the CNMC website. The list, described as for ‘anomalous behaviour’, is intended as both a deterrent and a basis for consumer claims. Minister of Economy Carlos Cuerpo stated:

“The anomalies that are detected will lead to the CNMC publishing a list of those establishments, of those petrol stations, that are having anomalous behavior in setting prices.”

Consumer complaint channels

Stations must set up a visible, accessible and free complaint channel on their premises and website, which must remain active for three months after removal from the list. If the final price is set by a third-party wholesaler, the station must provide the wholesaler’s identity and contact details to consumers.

Phased discount schedule

The fuel aid takes the form of a direct per-litre discount on the hydrocarbon tax, replacing the previous VAT reduction from 21% to 10%. The discount is 15 cents per litre in July, falling to 10 cents in August and 5 cents in September before expiring in October. For a 50-litre tank, this translates to roughly €9.10 saving in July, €6.05 in August and €3.02 in September. If the June 2026 year-on-year IPC for petrol or diesel exceeds 15%, the discount would rise to 20 cents in August and 15 cents in September.

Reactions

The Spanish Confederation of Service Station Employers (CEEES) warned that the fuel price at the pump has already risen overnight, contrary to government assurances.

“The slight temporary reduction in the IEH approved for July is absolutely insufficient to absorb the massive increase in international fuel prices.”
